Valtteri Bottas says his debut season in Formula One will be "all about learning" and that he won't put too much pressure on himself.

Having replaced Bruno Senna at Williams, Bottas steps up to a race seat following glowing praise from team principal Sir Frank Williams who described him as "quite simply one of the most talented young racing drivers I have come across" and added that "we expect great things from him in the future."

Bottas admits that his long-term ambitions match those of his team principal but for now he is focusing on building up experience in his debut year.

"Being successful in the future, that is my goal as well and I'm in F1 now because I really want to compete against the best in the world," Bottas is quoted by Sporting Life. "I want to do well and one day I want to be the world champion, but next year it's all about learning, getting up to speed as quickly as possible, minimising mistakes and bringing home points.

"I know, and the team knows, once I get to drive more, with mileage and experience, then I can do some good things."
